   6           USB Type-C Connector System Software Interface (UCSI) is a
   7           specification for an interface that allows the operating system to
   8           control the USB Type-C ports. On UCSI system the USB Type-C ports
   9           function autonomously by default, but in order to get the status of
  10           the ports and support basic operations like role swapping, the driver
  11           is required. UCSI is available on most of the new Intel based systems
  12           that are equipped with Embedded Controller and USB Type-C ports.
  13
  14           UCSI specification does not define the interface method, so depending
  15           on the platform, ACPI, PCI, I2C, etc. may be used. Therefore this
  16           driver only provides the core part, and separate drivers are needed
  17           for every supported interface method.
  18
  19           The UCSI specification can be downloaded from:

  22           To compile the driver as a module, choose M here: the module will be
  23           called typec_ucsi.

  31           This driver enables UCSI support on platforms that expose UCSI
  32           interface as ACPI device. On new Intel Atom based platforms starting
  33           from Broxton SoCs and Core platforms stating from Skylake, UCSI is an
  34           ACPI enumerated device.
